It delivers an HCSL output — the differential current-mode logic common in PCIe reference clocks and high-speed SerDes — across a supply range of 2.25 V to 3.6 V. ## Enable/Disable pin and power budget Maximum supply current when enabled is 42 mA; with the output disabled it drops to 22 mA — useful for power-gating clock trees in battery-backed line cards or fan-out buffers. ## Package, footprint, and layout fit Housed in a 6-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a seated height of 0.90 mm. The pad layout matches the industry-standard 5.0 x 3.2 mm quartz oscillator footprint — no board spin needed when replacing a quartz XO with this MEMS part.","metaTitle":"DSC1124BI5-100.0000 100 MHz HCSL MEMS Oscillator","metaDescription":"Active 100 MHz XO, HCSL output, ±10 ppm stability, -40°C to 85°C, 6-SMD package.

The 6-SMD, No Lead package (5.00 mm x 3.20 mm) uses the same pad layout as standard 5.0 x 3.2 mm quartz oscillators, so it is footprint-compatible without a board layout change."},{"question":"What is the output type and voltage supply range for this part?","answer":"Output is HCSL (differential current-mode logic). Supply voltage range is 2.25 V to 3.6 V, covering common 2.5 V and 3.3 V rails."},{"question":"Does the DSC1124BI5-100.0000 have an enable/disable pin?","answer":"Yes, the function is Enable/Disable. When disabled, maximum supply current drops from 42 mA to 22 mA."},{"question":"Can this MEMS oscillator replace an Epson or NDK 100 MHz HCSL quartz oscillator?","answer":"Functionally yes — same 100 MHz HCSL output, same 5.0 x 3.2 mm footprint, and wider supply range (2.25 V to 3.6 V). The ±10 ppm stability over -40°C to 85°C is comparable to or better than many quartz XOs. Verify the Enable/Disable logic polarity matches your design; the DSC1124 series uses a standard active-low or active-high pin depending on the suffix."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/DSC1124BI5-100.0000","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/DSC1124BI5-100.0000 when reusing this data.
